Due to recent events (I became a dad a second time 🙂 I revisited my audio baby monitor project for Raspberry Pis called Pifon. The former setup of having one Pi observing one room is not enough anymore and therefore the new version adds multi-room support!

In my plipbox project a fairly fast AVR 8-bit MCU with 16 MHz was connected to the Amiga’s parallel port to transfer incoming and outgoing IP packets from/to the attached Ethernet controller. A protocol on the parallel port was devised to quickly transmit the bytes in both directions. In version 0.6 a data rate of . . . → Read More: Amiga Parallel Port: How fast can you go?

It took quite a while to finish the release (over a year :)) but I think it was worth the wait:

A new parallel burst transfer mode was added that really improves the I/O speed on this Amiga port. You will get up to 235 KiB/s across the lines! Added new test modes for performance . . . → Read More: plipbox 0.6 released

When working with an Amiga running on a Minimig platform then data transfer is not as convenient as one might think: You have an SD Card connected and copying files around with SD Card is not the biggest deal, but unfortunately your Amiga is currently running from a system drive stored on this card :/ . . . → Read More: Networking on the Minimig with PPP and Roadshow

The Chameleon64 is a very powerful and versatile cartridge: Although its initially a C64 cartridge, it also runs standalone and allows to emulate different machines by replacing the FPGA programming. Today I use mine mainly as a HW Amiga emulator with the brilliant Minimig FPGA implementation.

With the ili9341fb driver I wrote for notro’s fbtft driver suite you can easily connect and use a Watterott MI0283QT9A display with your Raspi. For now you had to wire the display yourself to the Pi and a nice plate connecting the display was missing. Now the wait is over: Watterott designed the RPi-ShieldBridge! This . . . → Read More: Watterott’s new RPi-ShieldBridge

Notro has added a generic frame buffer driver called flexfb in his fbtft driver framework. This driver resulted from the observation that most small TFT driver chips share a lot in common like data transfer scheme, pushing pixels, and setting the update window. The only major difference is found in the initialization sequence required to . . . → Read More: Watterott MI0283QT-9 display with generic flexfb driver

Huh? Yet another plipbox release in such a short time, you might ask. While last time it was a software only update this time its a hardware update! I found such a nice new HW platform for the plipbox project that is really worth an immediate release…

In my last posts I showed how to integrate Watterott’s MI0283QT-2 and the newer -9 displays as a frame buffer device in Raspberry Pi’s Linux kernel. Now I will focus on adding support for the touch controller found on the display boards.
